Rockfour began writing and performing in Hebrew, and in 1991 released a single, "Haka'as" ("The Rage"), which did well on the Israeli rock charts.

After undergoing several lineup and stylistic changes, they settled on what would remain a fairly stable musical identity in 1995 with their second studio album, Ha'ish Shera'a Hakol (The Man Who Saw It All). The music of the album was firmly rooted in 1960's psychedelic rock and the band used vintage instruments and recording equipment. To complement the "sixties" setting, six music videos were published for song from this album, all in a consistent, distinctive style: they combined vintage footage made with amateur-class cameras with footage of the band in the same style. Though not initially popular, over time this album gained the reputation of being one of the best albums in Hebrew-language rock, especially among younger critics. After several years it was certified as a gold record for selling over 20,000 copies.

After In the late 1990s, the band began to write new material in English. During this period they recorded a studio album consisting of covers of classic Israeli rock songs by Shalom Hanoch and Arik Einstein, Behazara L'shablul. Ironically, though most of the songs were written during the psychedelic era, and Rockfour's covers were produced in their usual neo-psychedelic style, the original production on albums such as Shablul was fairly straightforward. In 1999 the band bid farewell to the Hebrew language with a live album (Behofa'a), in which they performed old and new material accompanied by a string section. The last track was a new studio recording titled "Mesibat Siyum" ("Graduation Party"), which literally translates as "Finishing Party".

Supermarket, released in 2000, was Rockfour's first full-length album in English. It received some attention outside of Israel (for example, from Allmusic), which encouraged the band to record another album of new material, One Fantastic Day, and begin touring internationally in 2001. Eventually they were signed to American label Rainbow Quartz. Their first release for the label was Another Beginning - a compilation of tracks from Supermarket and One Fantastic Day, which was followed by For Fans Only! - a collection of b-sides and live covers. During 2001 they produced and played on Shy Nobleman psychedelic pop debut album " How to Be Shy ", which became a hit in Israel.

During the recording of Nationwide in Detroit, Michigan in 2004, tensions began to develop between lead singer Eli LuLai and the rest of the band. LuLai left the band in the middle of the subsequent world tour. The remaining trio shifted around vocal duties and returned to performing the night after LuLai's departure.

Guitarist Baruch Ben Yitzhak took the role of lead singer for the recording of Rockfour's next album, Memories of the Never Happened, which was released through the Israeli indie label Anova Music. Keyboardist and multi-instrumentalist Yaki Gani was also added to the band after participating in the recordings, making them a quartet once again. In 2006 the groundbreaking artist management/ record label Anova Productions, founded by singer -songwriter and Midem Veteran Anat Damon, picked up the band. With the help of manager Hillel Wachs and after a long production process, the album was released in Israel in May 2007, and internationally on October 9, 2007 on Cooking Vinyl USA, with an accompanying extensive tour of the United States.

During the recording of Memories of the Never Happened the band recorded a cover of Pink Floyd's debut single "Arnold Layne" and submitted it to a competition created by David Gilmour in honor of composer Syd Barrett's death. Gilmour picked Rockfour's version as the best cover of the song, and the band won a day of recording at London's Abbey Road Studios. As of April 2010, these recordings have yet to be released. In June 2010, the band had released their first album in Hebrew from original materials with Anova Music. The album, Ha'olam Hamufla (The Wonderful World) gained the critics' love though the complexity of the materials that merged their psychedelic rock influences with more contemporary sounds in the style of the 00's Flaming Lips, The Shines and Grandaddy .

Starting with One Fantastic Day, they have incorporated the heavy, distorted guitar-sound of alternative rock, though it was toned down since the departure of LuLai. Live performances of older material maintain this style.
